Internal Modem

Connection to the internal modem is made via the RJ-11 jack, or two captured wire

connectors, located on the right side of the meter. Connect the meter to the

telephone network with an FCC Part 68 compliant telephone cord (that has two

male RJ-11 plugs).

If you have the captured wire connector option, connect the meter to the telephone

system with the (bare wire to RJ-11) cable provided. If you have the CTR-21

compliant internal modem option, you may also require an adaptor to interface

with your regional telephone jack.

1The baud rate used between connected modems is independent of the baud rate used for
communication between the modem and the 9300 Series meter.
Higher data rates can be achieved if data compression is enabled in the modem.
